What kind of symptoms/ severity of symptoms make you reschedule your appointment with your pdoc to be sooner than originally planned?

I do it all the time (rescheduling sooner) because when my symptoms worsen, I want to see my pdoc ASAP (some might say I'm a little high-maintenance, but really I often get very anxious and it becomes more urgent to see him).

Just curious as to what you guys would say about that. Especially when would you see your pdoc sooner about depression? My depression, obsession, and anxiety are bad enough right now for me to feel like I need to be seen sooner.
